Normal SEND and Enter already use opportunistic LXMF delivery. Make the long-press send-mode picker open on Send normally instead of Send as link so LoRa users do not accidentally choose link delivery as the apparent default.
This matches the field test result where short opportunistic LoRa messages worked bidirectionally, while link establishment from Ratspeak to rsDeck could queue after restarts/config changes.
Gate rsDeck opportunistic LXMF sends by the final packed Reticulum raw size when the next hop is LoRa, instead of using the pre-encryption LXMF payload size as the 254-byte limit.
Keep TCP paths on the normal Reticulum MDU, route LoRa packets that would exceed one RNode RF frame into link delivery, and log payload/raw/lora_raw sizing for field diagnosis.
Tested with rsDeck/Ratdeck T-Deck and Heltec V3 RNode attached over USB to a MacBook Pro running Ratspeak, using the medium-fast LoRa preset. Short 1-5 character opportunistic sends worked bidirectionally. Direct link delivery worked from T-Deck to Ratspeak/Heltec; Ratspeak-to-T-Deck link delivery later queued during link establishment while opportunistic still worked.
Adds an lxma://<hash>:<pubkey> QR overlay reachable from Settings and
from a new header row at the top of the Contacts tab. Including the
public key lets Columba/Sideband skip the PENDING_IDENTITY round-trip.
Contacts list stays visible even with no saved contacts so the header
row is always reachable; the empty-state floats above it.
Input events otherwise wait up to a full 33ms frame interval before
LVGL renders, which is noticeable when the loop body is loaded.
When the input poll reports activity, run lv_timer_handler()
immediately and let the next idle frame fall back to the 30 FPS cadence.
037af2a left the backlight at 0 in Display::begin() to avoid exposing an
unpainted framebuffer, but powerMgr.setBrightness() at step 24 only runs
at the end of boot, so the whole boot sequence rendered onto a dark panel.
Set PWM 128 right after the first lvBootScreen.setProgress(), once LVGL
has flushed the boot screen. powerMgr at step 24 still overrides with the
user's configured brightness.
